Question

Which is an equation of the given line in standard form?

A.
–8x + 9y = 23

B.
–8x + 9y = –23

C.
–8x + 7y = 25

D.
–9x + 8y = –23

Answer 1

I think its –8x+9y= =23

Answer 2

A .-.

Answer 3

@TheSmartOne @jordanloveangel could you check this if you know how to do ??

Answer 4

slope = (-1-3) / (-4 - 1/2)
slope = -4 / (-8/2 - 1/2)
slope = -4 / (-9/2)
slope = -4 * -2/9
slope = 8/9

y = mx + b
slope(m) = 8/9
(-4,-1)...x = -4 and y = -1
now sub
-1 = 8/9(-4) + b
-1 = - 32/9 + b
-1 + 32/9 = b
-9/9 + 32/9 = b
23/9 = b

y = 8/9x + 23/9 --- multiply everything by 9
9y = 8x + 23 -- subtract 8x
-8x + 9y = 23
yep...its A

Answer 5

@texaschic101 Thank you very much :D

Answer 6

im thinking
–8x + 9y = 23
